Roland, This tool is has been one of the favorite enhancements from SW2013. It reduces the number of clicks for any cutting line by picking up relations with the underlying features. In the example above by Daen, the number of clicks and mouse travel are actually drastically reduced. There are no more need for hacks and tricks to get the cutting line to line up with geometry. Additionally, it combines the old Aligned Section and Section tools, which means users don't have to keep track of which one they need (and they also don't need to restart or recreate views if they chose the wrong one or changed their mind later). The newer tool also supports many more scenarios that were previous broken between the two old tools.

In a couple weeks, when I'm working in a new place with this decade's version.

In my work, I'm more concerned with proper relationships of various parts. That's why I despise automatic relations. I don't want random coincident point on line when I need collinear with a specific edge or axis. It's just faster to draw with no automatic relations and place exactly what I need.

Paltry penalty in immediate "efficiency" with big payoffs in downstream robustitude. You can't take those saved mouse-clicks to heaven with you.
